Overview of Sunstar 42 Tooth Sprocket - 2-547442

High quality, all steel sprockets meet the demands of todays highest horsepower machines

Powerdrive countershaft (front) sprockets are manufactured from case-hardened chromoly steel for the ultimate in strength and durability

They also receive a parkerizing surface treatment for rust and corrosion resistance

Sunstar steel rear sprockets are manufactured from the highest quality 1045 high-carbon steel, and most are heat treated for added strength and wear resistance

Computer designed weight reduction holes are included where possible

Most rear sprockets are zinc plated, and some have a baked-on durable paint for corrosion resistance

Many conversions are available from unpopular 632 and 532 sizes to 630 and 530 sizes for better chain selection, as well as other lighter-weight options for racing

Any time you use other than the standard front/rear sprocket sizes, clearance must be checked. When converting to a smaller chain size, especially for racing, be sure to use the highest grade 0-ring chain available (non-O-ring heavy-duty acceptable for drag racing)
